Tired of being frustrated, frustrated being tired

working moms. it's rough. sometimes I resent my responsibilities at home for making me feel bad at my job. sometimes I resent my job for making me feel bad at being a mom. I definitely used to be better performing at work and had pride for being exceptional before having a baby and becoming a mom. now I feel like I am barely getting by. (first time in my life Ive thought it's possible I could be fired.) there are times where I feel like a really mediocre mom for being so tied up by work. tired of being frustrated. frustrated from being tired. anyone have any tips for easing the anxiety and down feelings? feels like there is no way to win. ***(quitting job isn't an option right now and husband is awesome just also working long hours).

***(I don't want to spend less time with my son so more help with childcare is not a solution).
